Scrape the gills from the mushrooms with a spoon and slice into 1/2-inch strips. Slice the peppers and onion.
Toss everything with the oil, fajita seasoning and 1/2 tsp salt.
Cook in two batches in a very hot large skillet or cast iron over high heat, 6-7 minutes per batch, until charred in spots.
Squeeze lime over the pan and toss.
Serve sizzling with warm tortillas, guacamole and pico de gallo.
